Board of CO~missioners, Cabarrus County, North Carolina <br />LAW ProPos~-I No. <br />April 1, 1991 <br />(Revised April 19, 1991) <br /> <br /> We understand that several methods of foundation stabilization were <br />proposed, but that undercut end soil replacement ia the method selected. <br />Other options ~iti~ly included sot1 ~ensification ~u~h t~e use of <br />compaction or vib~-replacement. In a~dition, the us~ of a slurry tren~ <br />a potenti~ option. We ~derst~d tha~ the options a~ve may be implement~, <br />if needed. <br /> <br /> Plus c~l for ~e m~n spillw~ support area to be'reinforced through <br />the use of mini-mugerc~t piles. We ~derst~d that the pedestri~ bridg~ <br />intake stmucture will be supported by steel H Piles and that the auxiliar~ <br />spillway is to be constructed using ~oller-compacted concrete. The dam <br />st~cture itself will ~ const~cted of sever~ specified soil t~es. <br /> <br /> ~e above info~ation w~ ob~ned f~m oum geotec~ic~ report (~W Job <br />No. CH 611~), dated April 6, ~9~, our review of the project specifications <br />~d discussions w~th Mr. Paul Watson of ~R, Inc. <br /> <br /> S~PE OF <br /> <br /> %~e propose to provide qu~ified engineering tec~ici~s to perform the <br />Collowing reporting, test~g ~d inspection se~ices which ~e e~ected to <br />r~uired on this pro~ect: <br /> <br />Soils <br /> <br /> - Monito~ undercutting of dam s~ructu~e to approximate gra~es shown on <br /> plus {/ncludinE shell ~ core).
